Abrasive Nozzle Nut 20454342 Waterjet Pump Parts
The part 20454342 is a precision retaining nut used to secure the abrasive diamond Orifice and Mixing Chamber assembly in IDE I/II style cutting heads on 60 000 psi waterjet systems. Machined from stainless sTeel with a 3/8″ bore, it threads onto the cutting head body to clamp the nozzle components firmly, ensuring leak-free operation under extreme pressures.
